Application and October 22, 1918. Serial No. 259,237. v

To all whom it may concern:

Be it known that I, MA'rrHEW C. SHARP broadly, to provide means for pumping oil,

or a mixture of oil and sand from oil wells, the construction to be such that the parts may be conveniently manufactured and assembled and will be convenient and durable in use. Other objects more specific will be explained hereinafter.

In the accompanying drawing which illustrates one embodimentof the invention, Figure 1 1s a-vlew 1n slde elevation of receivmg tanks for use in connection with the pumps, certain conducting pipes, a main discharge pipe, and valves being shown in longitudlnal section. Fig. 2 is a transverse section through-the strainer on line 2-2 of Fig. 7. Fig. 3 is a side view of the strainer. Fig. 4 is a detail relating to Fig. 1 to show the preferred mounting for amovable de livery pipe. Fig. 5 is a plan View of the tanks and their connections. Fig. 6 is a detail showing the preferred connection for the auxiliary conducting pipes with the main conducting pipe, a flexible section being shown partly broken away. Fig. 7 is a sectional -detail to clearly show the connection of one of the auxiliary conducting pipes with the discharge pipe, and the arrangement of the strainer, a nozzle and a stirring receptacle. Fig. 8 is a sectional view of the main discharge pipe looking toward its apertured flange.

Referring now to the drawing for a more particular description, numeral 1 indicates.

a' casing of conventional type used in oil wells, and which may have any required length, depending upon the depth of the well. I provide, within the casing, a main conducting pipe 2 having an apertured bot-v tom plate 3, and secured to said bottom 3 to project beyond the ends of the casing and main conducting pipe are a plurality of conducting tubes 4.

Numeral 5 indicates an apertured stirring receptacle which is mounted upon the outer ends of the tubes 4, and at 6 is indicated a cylindrical strainer interposed between the receptacle 5 and bottom 3. 'At 7 is indicated an inwardly projecting nozzle, its divergent end being mounted in one of the apertures formed in the top of the receptacle 5.

The parts thus described may be secured in connected relation by any suitable means, but: preferably the tubes 4 are threaded in the bottom'plate 3, as best shown in Fig. 7, and by use of nuts, 8 threaded on the lower ends of the tubes 4, the cylindrical strainer may be firmly secured in the position above mentioned, and the receptacle, 5 and nozzle 7 carried thereby will be secured to the bottom 3 of the main conducting pipe 2. Numeral 9 indicates a discharge pipe in communication with the nozzle 7 for use in elevatlng water, or oil and sand mixed with water.

Numeral 10 indicatesa pump adapted to be actuated byany suitable means for pumping water from the tank-11 and discharging to thep-ip e 2, said pump 10 being provlded with a supply ,pipe='12 communicating with tank 11 and having a pipe 13 in communlcation with said main conducting pipe 2, and it will be understood that when the pump 10 is actuated water will be delivered to the receptacle 5 from the pipe 13 and may 'pass upwardly through the pipe 9 to be delivered to the tank 11.

llumerals 14, 15 and 16 indicate tanks, eachbeing provided with a pipe 17 in communication with' an endless line pipe 18,

subject to a control of a valve 19, and at 20 are indicated a plurality. of pumps adapted be .actuated by-any suitable means for causlng water to be conducted under pressure to the discharge pipe 9 from the pipe 18 through pipes 21, said pipes 21 having any required length and being disposed in the annular chamber 22, intermediate the walls of pipes 2 and 9. r

The pipe 12 is provided with a valve 19, and while I have shown only one pump 10 for causing a discharge of water through the tubes 4, and through the receptacle 5 and the nozzle 7, it will be understood that the bore of the pipes may have any desired proportion, and the pressure of water in the pipe 2 effected by the pump 10 may be adequate to cause the water to move with great force for entering the discharge pipe 9. Also the pipes 21 may have any-required bore and may be of suitable lengths, and the pressure of water in pipes 21 provided by the pumps 20 may be adequate to cause engths of pipes 21 and the depth of the well,

' the result in operation being that oil or sand or oil mixed with .sand will enter the apertures a of the cylindrical strainer by operation of suction, and from thence Wlll move upwardly within the ipe 9, and will be discharged, its delivery eing to one of the tanks. l

Numeral 23 indicates a delivery pipe adapted to be swung horizontally on its mounting upon the upper end of the pipe 9, for delivering the mixture of water, sand and oil to any one of the tanks 11, 14, 15 or 16, said pipe 9 being at equal radial distances from the tanks.

- Water may be obtained from any suitable source for a movement through pipes 13 and 21 by operation of the pumps 10 and 20.

Since, as shown in Fig. 1, the pipes 17 and 12 communicate approximately midway between the tops and bottoms of the tanks, water practically free from sand or oil, will be supplied to the pumps, the oil .remaining in the upper part and the sand settling to the bottom of each tank. By use of any one of the valves 19 or 19, a tank may be se egated from the pipe 18 and the oil and ot er con-. tents of a tank, thus disconnected, may be removed, and on this account, a plurality of tanks and the movable pipe23 are deSlIed.

Each pipe 21, at its lower end, is provided with a curved discharge'nozzle b, as best shown in Fig. 7 which terminates approximately at the center of the bore of the pipe '9. Numerals 24 indicate a plurality of sleeves, the bore of each being formed outwardly divergent toward its ends, these being mounted in the pipe 9, and preferably threaded therein, with its lower end circumscribing a nozzle 6 of a pipe 21; and at 25 is indicated'a sleeve similar in form to a sleeve 24, said sleeve 25 being" threaded in the lower end of the pipe 9 to be disposed in an aperture of the plate 3 for maintainin said pipe 9 at the middle of the bore of the pipe 2. The sleeves provide for the pipe 9 a plurality of constricted passageways adjacent to the nozzles which aid materially in sustaining the weight of the column of water, sand andoil in said pipe while the pumps are operating.

The herein described mechanism is for use in instances where sand has been encountered in oil wells in such abundance that operation has not been practical, the sand being drawn toward and packed about the lower end of the pipe by suction, and operating as an obstruction to prevent pumping of oil. B J use of the herein described mechanism any sand, which otherwise might operate as an obstruction, will be removed, and for that purpose the strainer, best shown in Figs. 2 and 3, consists of a hollow cylinder provided with elongated intake apertures a, above mentioned, and having actuated, water may be discharged through said apertures for that purpose.

. The lower end of pipe 9 is provided with an outwardly'projecting circular flange26 having apertures f formed therein corresponding in number to the number of tubes 4, and as best shown in Fig. 7, the flange 26 is disposed on the plate 3, with its apertures f disposed in register with the tubes 4. However, in order that the Water may be retained in-the pipe 2 when the device is not in operation, and to prevent loss of time in refilling said pipe 2,- the pipe 9 may have a limited revoluble movement to dispose the apertures f in non-register with the tubes 4,

the pipes 21 moving with the pipe 9; and to permit this limited revoluble movement of the pipe 9 each pipe 21 is provided with aflexible section 27, as shown in Figs. 1, 5 and '6.

Fig. 6 illustrates a detail considered to be an advantage in construction, an apertured casting 27 being provided as a cap or headpiece for a mounting on the upper end of the main conducting pipe 2, suitable packing 28 and a packing-ring 29 being employed in connection with the outwardly projecting flange 30 of said pipe, and suitable packingrings 31 being employed for compressing the:

found to be of advantage to facilitate actuation of the pump 10 in certain instances, as when the pipe 2 contains water and when first applying power for actuating said pump 10. By opening the valve 38, water will move in a direction of least resistance,

this being through the pipe 37. As a feature of convenience in manufacture and for assembling the parts, sections 39 are provided for the pipe 9, and have a threaded connection therewith as best shown in Fig. 7 for a mounting of the nozzles b.

While I have described construction in de' tail, I do not wish to be understood as limiting myself in this respect, and changesmay be made in size, form, proportion and minor details, since the scope of the invention is determined by the appended claims.
